of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in ovens and more particularly to oven doors having transparent anels,the invention being applicable to oors for the ovens of cooking ranges, gas stoves or for portable ovens.

The object of the present-invention is to provide simple and efficient means for bolding the glass panel in placein such manner that liability of breakage thereof shall be reduced to a minimum.

A further object is to provide an oven door having a metal frame, with a glass panel which shall beheld in place without actual contactwitlrsaid cast metal frame "and without the use of packing strips.

inafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a. front elevation of an oven door embodying my improvements. Fi 2 is a rear view with the rear frame plate broken away. Fig. 3 is a longitudinal section, and Fig. 4c is a perspective view of the plate 1( 1 represents the main frame of the door and consists of a casting provided atits lower corners with pintles 2 by means of which the door can be hinged to the front plate of an oven. The upper member of the frame 1 is made intermediate of its length, with an enlarged portion 3 which forms a seat for a bracket 4 and this bracket carries a latch 5 and a handle 6 to operate the latch and manipulate the door. The

rear face of the frame 1 is provided near its I corners and also at intermediate points with bosses 7 having threaded sockets S'for the Ledges or seats 9 are formed around the inner edges of the frame 1 for the accommodation of a sheet metal frame 10. This frame 10 may be provided at its outer edges with flanges 11 which abut against the intermediate bosses 7 and in this manner the sheet metal frame 10 is held against displacement. The frame 10 is made in its rear face near its inner edges with grooves 12,said grooves causing the appearance on the exposed outer face of the sheet metal frame 10, of ribs or beads 13.

The inner edges of the sheet metal frame 10 adjacent, to the grooves 12, constitute a seat 14 for a glass panel 15.

A rear frame plate 16 fits within the main frame 1 and is provided with a series of holes for the passage of screws 17 which enter the threaded sockets 8 of the bosses 7 for the purpose of holding said sheet metal frame plate in place. The sheet metal frame plate 16 is provided at its edges with lugs 18 which project toward the sheet metal frame 10 and enter. the grooves 12 in the rear face of said frame. These lugs serve to prevent longitudinal and lateral displacement of the glass, panel and the portions of the inner edges of the frame plate 16 between the lugs 18 bear against the rear face of the glass panel near the edges of the latter so that said edges will be confined between the sheet metal frame 10 and the rear frame plate 16.

Rods 19 extend across the opening of the rear frame plate and the glass panel in said opening and the ends of said rods are made with perforations for the passage of screws 26, said screws also passing through holes in the rear frame plate and entering the threaded sockets 8 of the bosses 7.

Having fully described my invention what I claim as new and desire to secure by Letters Patent,

1. In an oven door, the combination with a main frame, of two sheet metal frames spaced apart to form an air chamber and cured to the main frame, one of said sheet metal frames having grooves or recesses in its rear face near its edges, a glass panel confined between said sheet metal frames, and theother sheet metal frame having lugs which engage the edges of the glass panel and enter said grooves or'recesses of the first JOHN R. CARTER.

mentioned sheet metal frame.
